nect the corrugated hose from the transition to the Trap. Secure

Cut an appropriate length of 2" PVC pipe, fittings and extension
pipe long enough to exit the cabinet and connect the vent drain to

els), or
• A 2" PVC coupling fastened onto the Drain Tee (*9MPD

Important: The pipe to the Tee Trap must be level or sloping to­
wards the Tee Trap
Connect the Tee trap and the main drain line exiting the casing as
shown in Figure 18.
Note: It Is recommended that all PVC piping and fitting connec­
tions be fit up and inspected before final cementing. Both the ex­
ternal Trap and the external Tee Trap must be primed before
operation. Verify all condensate drain connections are securely
clamped. A coupling and clamps (in loose part bag) may be
installed as shown for future servicing of the vent system.
